Foods that enhance a dog's immunity

Veterinary doctors agree that you shouldn't solely depend on commercial dog food, particularly kibble, to give your mutt all the required minerals and nutrients.

Give your loyal friend a stalk to chew three or four times weekly.

Poultry (turkey and chicken)

Turkey and chicken contain copious amounts of vitamin B6. 

Vitamin B6 is essential in a dog's immunity as it helps reduce inflammation and contributes to cytokine production.

Moreover, vitamin B6 aids in amino acid metabolism; these are antibodies and cytokines building blocks.

Studies have also shown that vitamin B6 participates in dogs' lymphocyte differentiation, proliferation, and maturation.

Buy boneless chicken or turkey breast and boil it thoroughly. Once it's cooked, you can mix it with the dog food or serve it plain.

Ensure there are no bones in the turkey or chicken meat as they can lead to choking or even puncturing the intestines.

Although some nutritionists argue that cabbage can encourage gas buildup if your dog consumes it regularly, it's still a healthy treat.

Cabbage also contains compounds that could prevent certain forms of cancer.

In addition, this crunchy vegetable can improve a dog's fur and skin by enhancing keratin production.

Remember that bananas have high sugar content, so you should feed them to your dog occasionally and in minimal amounts.

Huge canines like Cane Corso or Basset hounds can have half a banana once or thrice a week. Smaller dogs like poodles and chihuahuas will be glad to have a few tiny pieces.


Carrots are sweet, and almost all dogs love them due to their crunchy taste.

These root vegetables contain antioxidants and plenty of fiber. Additionally, carrots provide vitamin A, supporting organ formation in young dogs and enhancing immunity.

Some pet owners prefer serving the root vegetable cooked, which is okay, though cooked carrots won't do much for your canines' teeth.

Also, note that a canine's digestive system will not break down carrots completely. Hence you may see find some whole pieces in the dog's poop.

Start by offering a few pieces of the vegetable so your mutt gets accustomed to it and prevents diarrhea.

The vitamins present strengthen your dogs' bones and improve heart health. Lowering chances of your canine suffering from strokes.

For cranberry capsules, the rule is 400 milligrams capsule for medium-sized mutts and 250 milligrams for tiny dogs.


Blueberries are a superfood for various reasons; they contain antioxidants and can prevent obesity and heart diseases.

Blueberries may slow memory loss and overall aging if you have an older dog.

Red meat

Red meat provides dogs with iron, a critical component of the immunity system. Iron regulates cytokine production, compounds that trigger immune cells into action.

There are two types of iron, haem, obtained from meat, and non-haem, which comes from plants.

Studies have shown that a dog's gut digests and absorbs haem iron easily and faster than non-haem iron.

Even so, if your canine is allergic to red meat, it would be best to avoid it and use another food instead.
